Izzard/Izard Family

I have two family connections to this/these families. I have Rebecca Izard marrying Reverend Robert Braswell. Her father was John Izard.

I also have an Ann Izard(Feneryear)marrying #2 Michael Fulgham. Ann's father was Richard Izzard. Can anyone tell me if there is a connection between these two families or is it truely two separate family groupings. It seems too close not to be related somehow. Many thanks.
